morelenmir Posted February 17, 2016 Share Posted February 17, 2016 Is it possible for the SIO2SD to sit mid way in a daisy-chain of devices? Obviously one would need to modify it somewhat as mine has just one screw-down header on the main circuit board. I also only have the bare version so do not know if Lotharek's cased units come with two SIO sockets or just one. Presumably it would not be as simple as just wiring a socket in parallel to the connector? A second, unrelated (except in the general sense of modding the bare device) question; the SIO2SD website mentions that the hardware can support a wider display with I think 40 characters. Can anyone point out a part number or eBay auction for a compliant LCD unit? Quote Link to comment Share on other sites More sharing options...
Rybags Posted February 17, 2016 Share Posted February 17, 2016 It can but I see no reason not to just have it at the end unless you have problems with high speed that way. Fairly sure the homebuilt plans for SIO2PC include a "decoupling capacitor", no idea if SIO2SD has or needs one. 1 Quote Link to comment Share on other sites More sharing options...
Kyle22 Posted February 17, 2016 Share Posted February 17, 2016 It really doesn't matter where each device is connected in the chain. Obviously, some devices have no pass through connector and must be located at the end of the chain. This is only a matter of where you physically have an open socket. There are multi-port SIO connector boxes, and you can build your own. Simply connect all SIO pins together on a few SIO sockets. Any SIO device (using a 1050 as an example), that has two connectors has them wired together. No active components required. Without going into too much (probably boring to most) detail, SIO has a command line, unlike its direct descendant USB, which allows everything to be connected together without the need for a hub or similar device. For more info, ask Joe Decuir and look here: https://en.wikipedia.org/wiki/Atari_SIO and here: http://spiflash.org/atari/siospecs.pdf 2 Quote Link to comment Share on other sites More sharing options...
Rybags Posted February 17, 2016 Share Posted February 17, 2016 Another option which some take is putting it inside the actual computer though that then limits it's use to one machine. Or you could put it inside a peripheral, even powering it locally as well. 1 Quote Link to comment Share on other sites More sharing options...
morelenmir Posted February 17, 2016 Author Share Posted February 17, 2016 I would quite like to have it and an SIO2PC-USB connected, using the latter with the 'SIO2BSD' application on a Debian machine to provide an R/W 'harddrive' folder via the 'PCLink' software. Or at least I can see that as a useful combination if one is running the A8 without mods like Ultimate1MB and SIDE2. Quote Link to comment Share on other sites More sharing options...
flashjazzcat Posted February 17, 2016 Share Posted February 17, 2016 No problem here connecting the older SIO2SD boards anywhere at all in the chain, simply by wiring another male SIO connector to the IO header as a pass-thru. Extremely useful if you wish SIO2PC, for example, to be the last in the chain, although that's incorporated in a couple of the newer SIO2SDs.

+CharlieChaplin Posted February 17, 2016 Share Posted February 17, 2016 Well, I have two SIO2SD in a 1010 case, using a part of the original 1010 pcb with two SIO sockets, thus daisy-chaining them isn`t a problem. 1 Quote Link to comment Share on other sites More sharing options...
rhfil Posted February 17, 2016 Share Posted February 17, 2016 Where does one buy a SIO2SD with USB on one end and Atari floppy drive cable on the other? Quote Link to comment Share on other sites More sharing options...
